Zotac's Ion: The World's First mini-ITX Ion Board

Blu-ray Playback: It Works Quite Well
I tried using the Zotac Ion to watch Blu-ray movies, after all, that’s one of the major reasons to get this thing over the much cheaper Intel alternative. NVIDIA’s Ion chipset (aka GeForce 9300) can fully decode H.264 and thus make high definition movies watchable on the otherwise incapable Atom CPU.
Anything that supports NVIDIA’s PureVideo HD will work on the Ion board, in this case I used Cyberlink’s PowerDVD 9 Ultra - the latest version off of Cyberlink’s website. I fired up Casino Royale and watched, the CPU utilization across all four virtual cores (two physical cores) ranged between 19 - 27% on average. At times I saw steady peaks at 36% and the highest I ever saw was 50% in an unexpectedly stressful scene. With the dual-core Atom, I never saw any dropped frames.
The high CPU utilization is simply due to the content decryption required by every copy protected Blu-ray disc, the actual decode is being done completely in hardware. If you playback an unencrypted Blu-ray disc you get CPU utilization in the 10 - 14% range.
Earlier versions of PowerDVD were not well optimized for Atom, but the latest updates to PowerDVD 8 and PowerDVD 9 ensure smooth playback on even a single-core Atom/Ion system (I used an older version of PowerDVD in my short lived Ion Blu-ray Investigation which was the cause for poor performance in those tests). Note that at one point in my testing I saw the CPU usage hit 50% on the Atom 330, which means it would be at 100% with an Atom 230. The spike only lasted for a second or two but it's possible for a single-core Atom setup to stutter in situations like that if you have a background task running at the same time.
You can even get hardware acceleration using the Ion board under Media Player Classic - Home Cinema. Using the latest stable build of MPC-HC you simply need to go to the Options menu (View -> Options) and configure a few items. Click on Output then select EVR or EVR Pres. if you want to enable subtitles.
Then click on the Internal Filters option and disable all FFmpeg transform filters, enable all DXVA transform filters and enable the Matroska source filter (for playing back MKVs).
If you configure MPC-HC as I described above you'll get full hardware acceleration on the Ion board. This is a great way of watching your own ripped content. Without encryption CPU utilization ends up being in the 10 - 14% range, allowing you to even do things in the background while you're watching a video. I would caution you against doing too much however, so much as scrolling the volume slider up/down will cause the video playback to stutter. You're probably better off just being happy that you're not dropping any frames and not touch anything while you enjoy your movie.

I need a ITX with PCI-e 1x slot. ANyone seen such an animal?dingetje - Tuesday, May 12, 2009 - link
@Pandamonium,No it was not rude; flipmode was obviously joking about the funny sounding line in the article.
Lighten up...

Yeah, it did sound pretty rude, but I was just giving him a hard time.Anand Lal Shimpi - Tuesday, May 12, 2009 - link
I didn't intend for the line to sound like that, I meant that after our first review went up there was a great amount of interest in an Ion motherboard from our readership. I'll update to clarify.I stuck with the x264 test for power consumption since we've used it in previous reviews and I needed a good way of comparing power consumption to other systems that can't play back Blu-ray content.
Take care,
Anand

I did not mean to sound too snotty, but I do enjoy being a smart ass once in a while. Maybe a :wink: would have been better than a :roll:As for power consumption, using x264 encoding does make sense for most reviews, but it seems a bit of stretch for this one. I sure do feel bad for anyone encoding x264 with an Atom. Do you think it is safe to say that the power consumption would be at its highest when the IGP is under load?
Anand Lal Shimpi - Tuesday, May 12, 2009 - link
I agree, in hindsight I should've probably done a load test with the GPU being stressed as well. I'll try and look at that if I do a followup.The power consumption of the Ion/GF9300 chipset should be higher than the dual-core Atom CPU, so anything that stresses the GPU should deliver the highest power consumption. Note that Blu-ray playback uses the PureVideo HD engine which is actually separate from the shader processors on the GPU, it's a separate set of functional blocks on the die. I wouldn't assume that BD playback would generate the highest power consumption values, playing a game might do the trick for that.
Take care,

Anand, Thanks much for the review. I have been wondering much about this platform since I first read the ads on nVidias webpages.Here, we live off grid, and are entirely powered by solar + wind (and the occasional running of a 30kW gen to pump water). What I was hoping to see here, was something that could play games fairly well at medium settings, do photoshop tasks fairly well, and play movies well also. I was fairly certain the latter would not be much of a problem, but the former two might have been. According to your benchmarks, it looks like my guess was not too far off.
Also, your review came about two days too late concerning a decisions I was making concerning getting a newer system for above duties, while keeping power usage down to a minimum. That however is not your fault, and probably made my decision much easier.
Now, I would like to add that the Zotac board with ATX power connectors is it ? May actually be a better overall option for some, including myself, *if* "we" can find a good sub 100W 80 Plus PSU. Once you get down to around 50-60W of system usage, the 50% PSU power out/usage combination is what can, and does kill power efficiency according to what I have been reading(e.g. for best efficiency, loading any PSU is usually optimal at 50% load capacity). George Oui from ZDNET tech articles (sorry may have spelled his last name incorrectly, I do not have the link handy) has done some experimentation on the subject, and at the time of his findings the best PSU he was able to find was the sparkle 220W 80 Plus PSU ( the PicoPSU's did not seem to do as well ). Anyways, he was able to get a complete Core 2 system, including an LCD monitor down to a sipping 49W of power usage while under load I believe. Personally, I consider that pretty good.
Anyways, thanks again, and I for one would love to see more articles along these lines.

Why not simply run something downclocked? Low-power parts or simply a laptop with a discrete GPU is also a possibility. Or even something like the Fujitsu Amilo Sa 3650 with graphic booster (external mobile HD3870).BTW the Zotac board comes with a powersupply and doesn't have an ATX connector in this version Anand reviewed.

The Pico-PSU efficiency is going to be rather dependent on the efficiency of your AC to DC conversion. They claim over 95% DC-DC efficiency, so if you have an efficient method of directly feeding them regulated 12V they probably do pretty well. I suppose if you needed multiple workstations you could use one ATX PSU to feed regulated 12V to a bunch of Pico-PSUs and get the load on the ATX PSU up to the range it likes. Otherwise, I'm not sure how efficient those bricks are at Ac to DC.therealnickdanger - Wednesday, May 13, 2009 - link
Great review, thanks!Speaking of GPU tests, I have seen other reviews of Ion showing Left 4 Dead playable at 25fps and WoW (720p, low details) playable at 50fps! How come your rates are so low?
I think it would be appropriate to follow up with testing of games like UT2004, Halo PC, COD4, Battlefield 2, and Counter-Strike: Source. Obviously, Crysis would be a waste of time on this platform, but some slightly older games that are still played heavily online and at LAN parties are ones I would really like to see benched.
Nothing would excite me more than to have a portable, cheap, fanless, low-power, Mini-ITX gaming machine for some of the games listed above. If it can manage 25-30fps at or near 720p without looking like a turd, that would be more than acceptable. Please don't make me buy one and benchmark it myself! ;-)
